I have a 1977 GB36 insured with Gieco/BoatUS and it's under $1,500 a year full coverage. Including the replacement value from the surveyor.

As Snotter had mentioned there is a tech repair manual with a flow chart for idiots. I'm the idiot that needs the flow chart.

Thanks Gilberto I have this manual I'm looking for the Tech Repair Manual

Thanks All! Snotter I have now joined smokstak but am waiting approval before I can post or search. Do you have the manual's #? What rotary switch are you referring too? The one at the remote start that changes from shore to genny?

Sorry its an Onan MDJE not a MDJA

Hi All I have a 1977 Onan MDJA 7.5 that has not been running in a while. I go to start it and it fires up right away but dies as soon as I release the start switch. At this point I went down to the engine room to investigate and tried holding the start/stop solenoid in the run position and hit...

Great where are the safeties?

Okay I was at the boat today and tried the switch with no luck. I noticed that the solenoid doesn't activate during preheat but does during start.

I cracked the bleedoff return line and let it pump so it's not air in the lines. I will try switching to the genny.

Xsbank I thought that too and even hot wired the fuel pump directly to the battery, same result.

As soon as I start cranking the engine the oil pressure gauge starts to climb. Where are these safeties?

Yes I have oil pressure, Yes its on shore power.

Hi All I have a 1977 genny that I haven't used in a while so I decided to change all filters, oil and replaced the battery and the manual fuel pump with an electric unit. After bleeding the system I press the start button and it starts right up but dies as soon as I release the start button...

Hi I'm interested in the props.

Okay now the wiring question. The stop solenoid is a Prestolite with one terminal IGN and the other SW and I think the mount is the ground. What terminals should I use?

Thanks guys I ordered on off ebay and started to make the cover plate.

Thanks Ksanders Could you recommend a pump and relay?

Hi All I too have lost the use of my transfer pump and am trying to understand the switch to an electric pump. Is this a matter of removing the existing unit and sediment bowl, blocking off the block opening and replacing with a inexpensive electric pump? How do I wire the new pump? Anybody...

Hi All I purchased a boat that has sit for awhile and need some help with the Raritan Crown head and Electro Scan. First off nothing was working and the bowl was empty. I checked to see if the system was getting voltage and discovered that the main fuse was blown (35 amp) I replaced this...

Hi All I have a Mase Mariner 4k genny that needs a wet exhaust elbow. I called Mase and they no longer make this part. Has anyone here made one or have one for sale? Thanks

Thanks RT The boat was on the hard when I tried but is now back in the water. I can now start the engines to heat them up. How do you plumb this pump? I don't think I can access the bottom of the pan.

Hi All I wanted to change my oil on a pair of Perkins 4.154's and had no luck. I started with a Temco hand pump through the dipstick, Nothing then changed to a Jabsco drill pump, no luck. I then borrowed my buddies pump rig, once again no luck. The engines were cold and the oil looks pretty...

So after reading all the reply's I did a google search on Delo 15-40 and some guy was selling 6 gallons on Craigslist new in case for $50.00. I now have 6 gallons of it.:thumb:

OK So what would happen If i use the Delo 10-40 like Sunchaser suggested?

Thanks for the information! I checked the manual and It list's everything from 20-50, 10-30, 20-20, 20-40, 20-30 from different manufactures. Delo makes a 20-40. Am I over thinking this?
